How to Replace a Coolant Temperature Sensor The first thing is remove the electronic harness that connects to the sensor. Typically this sensor is attached with a plastic clip. To remove the clip, take a flat head screwdriver and slowly pry the clip from the outside edge of the temperature sensor. Step 8: Remove the coolant temperature sensor. Using a ¼ drive socket and extension and the correct sized socket (usually 19mm), loosen the sensor from the engine block and remove it entirely.

- Engine Coolant Temperature (ECT) sensor 2 is a thermistor attached to the radiator. The Powertrain Control Module (PCM) applies voltage (about 5 V) to the ECT2 signal circuit through a pull up resistor. As the engine coolant temperature cools, ECT sensor 2 resistance increases, and the PCM detects a high signal voltage.

Coolant Temperature Sensor The coolant temperature sensor, which is commonly located near the thermostat, helps in keeping engine heat at an appropriate level. As its name implies, the coolant temperature sensor measures just how hot or cold the engine is. The cooling system uses that information to effectively deal with the engine temperature.n fact, you can get a brand-new OEM coolant temperature sensor for as low as $5! There are variants though that can cost as much as $30, but they're still inexpensive by any means. Installing an OEM coolant temperature sensor shouldn't prove to be much of a challenge too, especially if you're an experience DIYer.

What is a Radiator Flush? Once the drain plug is removed, the old coolant should drain into the receptacle. This liquid should never touch the ground or be left near pets or small children. Engine coolant may taste sweet to a pet, but it is highly poisonous. The next step is to replace the drain plug and open the radiator cap. The mechanic should pour the entire contents of the coolant/detergent solution into the radiator through a funnel, then top it off with clean water.
